intel UHD graphics no HDR

can someone help me solve the problem with the HDR option connected to intel uhd graphics 630 last drivers

my processor intel i7 8700k motherboard Fatal1ty Z370 Professional Gaming i7 nvidia 1080ti

the problem is that the HDR option is not available in windows 10 vers1709 bulid 16299.125 when connected is to intel graphics

if the connection to the nvidia card HDR is available .

as it is connected to nvidia dxdiag shows DXGI_COLOR_SPACE_RGB_FULL_G2084_NONE_P2020, that indicates
that this is for HDR10 and the connection is displaying advanced color.

when to intel show DXGI_COLOR_SPACE_RGB_FULL_G22_NONE_P709,that
indicates this is sRGB and not advanced color.

intel support claims that this is the fault of windows

please help thanks

Use my GPU instead intel UHD graphics

I'm testing windows 11 in my ThinkPad X1 Extreme and the transitions on the desktop are horrible laggy, i trying to change the default graphic card to NVidia instead intel UHD, this is possible?

 

Intel graphic card disappeared

I have a Lenovo Legion Y540 laptop with Windows 10, Intel i7-9750H processor, Intel UHD Graphics 630 and NVIDIA GeForce GTX 1650 graphic cards. The Intel graphic card is gone from device manager, it is not hidden, I also tried adding it manually but it isn't
found. The current driver says that it is not available, when I tried downloading the new ones, after launching it says that "the computer does not meet the minimum requirements for installing the software". The Intel Support also doesn't discover the card.
When I switched the graphic device in BIOS to switchable the laptop was stuck on startupand never powered up. I recently updated my Windows (1909) and I suspect it might have something to do with that.

Thank youin advance for your answers.
